I’m scared the water can kill my Betta. I have had a male Betta for a couple months now. He has been inside a 2 gallon tank and I change the water regularly and clean the gravel. Yesterday I decided it’s time to get him a 5 gallon tank so he can have more room to swim. Along with purchasing the 5 gallon tank, I decided to change the gravel color to blue so I bought Aqua Culture gravel in blue. I rinsed them for quite some time to prevent the blue to dye the water in the tank. After cleaning them I put them in the tank and added my water that I left out for a day. The water looks blue on top but in the swimming space between the gravel and top of the water, it looks as if there is a blue tint. I’m scared to put him in the water I take very good care of him he’s my only pet. Please help me I need to get him out of the 2 gallon tank because his behavior may be indicating stress and I don’t want that for him.
